I was telling her where to set the air inlet dial on the Mark III, after I had loaded it to the brim with coal, and let it sit with the ash door open to get a good bed burning. I said to her, "do you know what that is set at right now (how many turns out)? Do you know how to find out?" She said no, so I proceeded to show her .... with my face about 3" from the glass. No flame showing, & a bright glow in the pan .......
It was open 1-1/2 turns, so I turn it in & say, "half, one, half ....." BOOOOOOOOOOM!!!
Just as the dial was completely shut, I saw a flash of light & my hair blew back (and I don't have much hair, mind you!
Was a hell of a show, let me tell ya!! WOW!!


Much more difficult is turning it down
All kidding aside, she will observe me with good intensions but it's not her thing. While taking the ash tubs outside and replaced the one in the stoker I forgot to restart the master switch 
LMAO! priceless
